Works for me. Both in debug and release configuration. We also tested successfully on Ubuntu. So probably there is still some modification you forgot, an erroneous build, or anything like that. As I cannot reproduce anything of what you experienced I would recommend that you do a clean clone/build without any modifications and try again, sorry. :/

To help you out here, we need more information about your setup. We also need to know if it works for you unmodified? By the way, you don’t need all that string handling stuff in your additional code, as mitk::IOUtil::Load() takes a std::string as its first argument – just call mitk::IOUtil::Load(imagePath.toStdString(), *ds).

I guess you are reading an outdated version of our tutorial (which would also explain why you are using the deprecated DataNodeFactory instead of IOUtils). There are some major differences in the current version (MITK 2015.05): http://docs.mitk.org/2015.05/Step01Page.html Do you really want to code your own application from the very beginning instead of just using/extending the full-featured MitkWorkbench? Regarding MITK images in QtWidgets: I found a code snippet in my archive which I wrote a few years ago. I cannot guarantee that it will still work out of the box but you should get the idea of what is necessary to accomplish that task (see it as pseudo code). Maybe Rostislav has a better snippet (as far as I remember he displays images in his widgets, too - added him explicitly to Cc): SNIP ==== mitk::ExtractSliceFilter::Pointer extractSliceFilter = mitk::ExtractSliceFilter::New(); extractSliceFilter->SetInterpolationMode(mitk::ExtractSliceFilter::RESLICE_CUBIC); extractSliceFilter->SetResliceTransformByGeometry(image->GetGeometry()); extractSliceFilter->SetWorldGeometry(planarFigure->GetGeometry2D()); extractSliceFilter->SetVtkOutputRequest(true); extractSliceFilter->SetInput(image); extractSliceFilter->Update(); vtkImageData* imageData = extractSliceFilter->GetVtkOutput(); mitk::LevelWindow levelWindow; imageDataNode->GetLevelWindow(levelWindow); vtkSmartPointer<vtkLookupTable> lookupTable = vtkSmartPointer<vtkLookupTable>::New(); lookupTable->SetRange(levelWindow.GetLowerWindowBound(), levelWindow.GetUpperWindowBound()); lookupTable->SetSaturationRange(0.0, 0.0); lookupTable->SetValueRange(0.0, 1.0); lookupTable->SetHueRange(0.0, 0.0); lookupTable->SetRampToLinear(); vtkSmartPointer<vtkMitkLevelWindowFilter> levelWindowFilter = vtkSmartPointer<vtkMitkLevelWindowFilter>::New(); levelWindowFilter->SetLookupTable(lookupTable); levelWindowFilter->SetInput(imageData); levelWindowFilter->SetMinOpacity(0.0); levelWindowFilter->SetMaxOpacity(1.0); int dims[3]; imageData->GetDimensions(dims); vtkFloatingPointType clippingBounds[] = { 0.0, dims[0], 0.0, dims[1] }; levelWindowFilter->SetClippingBounds(clippingBounds); levelWindowFilter->Update(); imageData = levelWindowFilter->GetOutput(); QImage inspectImage( reinterpret_cast<const unsigned char*>(imageData->GetScalarPointer()), dims[0], dims[1], QImage::Format_ARGB32); inspectImage = inspectImage.rgbSwapped().mirrored(false, true); // Important, don't forget!! m_Controls.inspectLabel->setPixmap(QPixmap::fromImage(inspectImage)); === SNIP ________________________________________ Von: Sina Gerlach [sina.gerlac...@gmx.de] Gesendet: Dienstag, 13.

Instead of having it in the command argument thingy I want to open an image using QfileDialog which works but its not displaying the image yet.
